BACKGROUND OF THE INVENTION

[0001] (a) Technical Field of the Invention

[0002] The present invention relates to a portable electric-poweredtool, and in particular, to a tool having an independent tool connectorand a holding body.

[0003] (b) Description of the Prior Art

[0004] Referring to FIGS. 5 and 6, there is shown a conventionalportable electric-powered tool having a folding head design. The end ofthe two sides of the tool connector 30 is extended to form a pivot plate31 for the pivotal mounting by a pivot axle 32 with respect to theholding body 33. The tool head can be adjusted in accordance with therequired position and angle. However, these parts are integrally formedwith the tool as the essential components of the tool. These componentscannot be separated for use with a different tool connector and cannotbe applied to a different tool connector 30 with the same holding body33. Accordingly, it is an object of the present invention to provide aportable electric-powered tool which mitigates the above drawbacks.

SUMMARY OF THE INVENTION

[0005] It is an object of the present invention to provide a portableelectric-powered tool having a holding body containing a battery module,a press switch, and a tool connector, wherein one end of the holdingbody is formed into a recessed insertion hole having two internal sidescorresponding to an inner edge face being disposed with an engagingstripe, the stripe is provided with a conductive plate for connectionwith the battery module in the course of inserting the tool connector,the ring face of the tool connector is easily positioned by engagingwith the insertion hole and a copper plate connection point at thebottom of the insertion hole.

[0006] Yet another object of the present invention is to provide aportable electric-powered tool, wherein the tool connector is flexibleto be replaced so that the cost of purchasing the essential componentsof the tool is greatly reduced.

[0007] A further object of the present invention is to provide aportable electric-powered tool, wherein the tool connector is a mountingfor a bi-directional tool.

[0008] A further object of the present invention is to provide aportable electric-powered tool, wherein the inner edge of the extendedside end of the insertion hole is a protruded engaging edge which isperpendicular to the stripe.

[0009] The foregoing object and summary provide only a briefintroduction to the present invention. To fully appreciate these andother objects of the present invention as well as the invention itself,all of which will become apparent to those skilled in the art, thefollowing detailed description of the invention and the claims should beread in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] The following descriptions are of exemplary embodiments only, andare not intended to limit the scope, applicability or configuration ofthe invention in any way Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

[0018] Referring to FIGS. 1 to 4, there is shown an electric-poweredtool having a body 10 comprising two hollow housings. One end of thebody 10 is formed into a recessed insertion hole 11 and the hollowinterior of the body 10 is provided with a directional switch 12 at thetop edge thereof for triggering the clockwise or counter clockwiserotation of the tool. The hollow interior of the holding body 10 is alsoprovided with a battery module 13 as a power source supply. The batterymodule 13 is directly placed within the internal bottom portion, andcorresponding to the lower edge of the handle of the tool, a startswitch 14 is provided, facilitating to control of the tool by pressingto connect to the current supply. A battery-charging seat 15 which isconnected to the battery module 13 is provided at the upper elbowjunction of the tool so that external current is used as a source forcharging batteries.

[0019] The interior of the insertion hole 11, corresponding to the inneredge, an engaging stripe 16 is provided, and a conductive plate 17 isformed at the stripe 16 to connect the power source wire to the batterymodule 13. The inner edge of the two sides of the insertion hole 11 isprovided with the protruded stripe 16 perpendicular to an engaging edge18 for the mounting of the stripe 16 so as to stabilize the positioningof the tool connector 20, supplementing the safety in the course offabrication process of tools.

[0020] The tool connector 20 is an elongated tubular body and has asubstantially conic shape facilitating the insertably with the insertionhole 11. The hollow interior is provided for the mounting of atransmission motor 21 having transmission gears at the sides thereof Thetwo end sides of the tool connectors 21 are mounted with a power outputfacilitating installation of fabricating tool 22, such as a drill, screwdriver, etc.

[0021] The two ends can be mounted with different tools 22 for differentapplication options. In order to facilitate the insertion of the toolconnector 22 with the insertion hole 11 of the holding body 10, theinterior of the insertion slot 11, corresponding to the protruded stripe16, at the external ring face of the tool connector 20, a recessedinsertion slot 23 is provided, such that the connection wire of themotor 21 is connected to the copper connection point 24 at the bottomcenter of the insertion slot 23 to provide operation, such that when thetool connector 20 is inserted with the protruded stripe 16, the toolconnector 20 can be safely use. The protruded engaging edge 18 can beengaged with the slot 25 to ensure the tool connector 20 and the body 10being connected. The controlling of the switch 14 allows the tool to beoperated.

[0022] In accordance with the present invention, the easy insertion ofthe tool connector 20 allows the entire tool structure to be able toreplace some components if it is required.

[0023] It will be understood that each of the elements described above,or two or more together may also find a useful application in othertypes of methods differing from the type described above.

[0024] While certain novel features of this invention have been shownand described and are pointed out in the annexed claim, it is notintended to be limited to the details above, since it will be understoodthat various omissions, modifications, substitutions and changes in theforms and details of the device illustrated and in its operation can bemade by those skilled in the art without departing in any way from thespirit of the present invention.
